Taking responsibility is by far the most important of the 10 Skill Sets. You are not born a winner. Your parents, friends, teachers, mentors, or whomever else is in your life cannot give you all 38 skills from the 10 Skill Sets. They may help you practice and reflect on all those skills, but only you can decide to be a skills winner for yourself.
That means you cannot blame your lack of skills on anyone but yourself. Students or employees who mess up and then whine that assignments were not clear are playing the blame game. There is no more direct path to failure than failing to take responsibility for one’s self.
People who are self-motivated, ethical in their dealings with others, and that manage both their time and their money well are winners.
